McBride 2026 (WBLT)
About this reference
McBride et al. (2026) provide adult age- and sex-specific reference ranges for the distance-based Weight-Bearing Lunge Test (WBLT), a knee-to-wall measure of ankle dorsiflexion in centimeters. The study reports subgroup means, standard deviations, sample sizes, and percentile-derived clinical category cut-points across seven adult age groups.
Known limitations
- Healthy volunteer sample from Canada, Spain, and Iran; values may not generalise to all countries, athletic populations, or symptomatic clinical populations.
- The source publishes empirical category cut-points rather than a complete P5/P25/P50/P75/P95 table. This site uses the published category boundaries for P5, P25, P75, and P95.
- P50 is estimated from the subgroup mean because an exact empirical median is not published in the article. The central value displayed on age/sex pages is therefore the subgroup mean rather than an empirical median.
- Distance-based WBLT values are not directly comparable to angle-based ankle dorsiflexion measurements in degrees.
- Cross-sectional design reflects differences between age groups, not individual ageing trajectories.
